Here we have some evidence that pre-biotics containing bifidobacterium can be helpful in restoring gut permeability to normal levels and in reducing oxidative stress and inflammation ( at least in diabetic mice). Several hundred species of bifidobacterium exist. They are the lesser-known cousins of the acidophilus bacterium. Gut. 2009 Aug;58(8):1091-103. Epub 2009 Feb 24. Links Changes in gut microbiota control inflammation in obese mice through a mechanism involving GLP-2-driven improvement of gut permeability. Some more on bifidobacterium http://www.raysahelian.com/bifidobacterium.html Bifidobateria and Probiotics in Health and Disease Like its better-known cousin acidophilus, the bifidobacteria group (often simply called bifidus) is considered a "probiotic." Bifidobacteria are one of the hundreds of beneficial bacteria that inhabit the body's intestinal tract, and help to fight off infection. five Probiotic bacteria with bifidobacteria are effective in preventing and reducing the severity of acute diarrhea in children. They are also useful in antibiotic associated diarrhea but not for elimination of Helicobacter pylori. In inflammatory bowel disease, especially ulcerative colitis, probiotics with bifidobacteria offer a safe alternative or addition to current therapy. Bifidobacteria have been used to prevent urogenital tract infection with benefit and, perhaps more intriguingly, to reduce atopy in children. Probiotics do not always work. Bifidobacteria strains Despite the generally accepted importance of bifidobacteria as probiotic components of the human intestinal microflora and their use in health promoting foods, there is only limited information about their phylogenetic position, physiology and underlying genetics. In the last few years numerous molecular approaches have emerged for the identification and characterization of bifidobacterial strains. Bifidobacterium types or strains Bifidobacterium adolescentis bifidobacterium bifidum Bifidobacterium breve bifidobacterium infantis B. lactis bifidobacterium longum Bifidobacterium pseudocatenulatum B. pseudolongum Bifidobacterium questions Q. Are there any interactions with using a bifidobaterium supplement with 5-HTP supplement or lipoic acid? A. I don't see any problems using bifidobateria with these supplements. Health Benefit of Prebiotics for bifidobacteria growth There is increasing awareness that bacteria in the human gut play an important role in maintaining health, both within the gastrointestinal tract and the rest of the body. One can increase the number of good bacteria in the body in two main ways: By taking probiotic supplements or eating yoghurt which directly supply good bacteria to the colon, or by ingesting prebiotics which help stimulate the growth of good bacteria.
